Issue Details

I want to find how the digital ports and lines of my C-Series Digital I/O Module align with the pinout, but can't find that information under the device's specifications or manual.

Solution

  1. Open NI Measurement & Automation Explorer.
  2. If you don't have the physical device connected, you can create a simulated device .
  3. Open a Test Panel for your device.
  4. After selecting a port under Port Name, you should see one of two things:
  • If the indicators and All Input/All Output options are greyed out, the port you selected is either a digital input or digital output (whichever row of indicators is filled in).
  • If the indicators and All Input/All Output options are NOT greyed out, the port you selected can function both as a digital input or output.

The line numbers match with the numbers indicated by your specific device's pinout .
